Abstract

Devices and methods for information processing in optical communications are provided. In its simplest embodiments, collimated light (1) passes through a non-grating diffractive structure (2) and a lens (3). The light is spatially processed in the focal plane (4) of the lens (3). Thereafter, the light can, for example, be coupled into a fiber or detector array (5).
